FASTENEB.

Application filed March 1, 1928. Serial no. 253.2815.

My invention relates to fasteners as a class.

The object of my invention is to provide a fastener of a bolt type,which may be in stalled and used for window sash and doors. The bolt isconstructed without the common type of threading, tapping. screws,rivets or springs, and may serve both as a sash fastener and a lift. Itis easily and quickly placed in operative position in new or old sash,without weakening the same, and will secure them so as to obviate play,as well as operating for an effective fastener. These objects, as wellas other advantages, I attain by the construction, combination andarrangement of parts illustrated in the accompanying drawings which forma part hereof.

Fig. I is a front elevation of the device placed in operative positionin sash stiles, partly shown.

Fig. II is a sectional view of the bolt with fastening latch in thehandle thereof, as on line IIII in Fi I.

Fig. III is a p an view of the device with the fastening latch in thehandle.

Fig. IV is a front elevation of the bolt showing central groove toreceive the handle with fastening latch.

Fig. V is a detail of the handle showing long vertical slotto receivethe fastening latch.

Fig. VI is a detail View of the fastening latch.

Fig. VII is a plan view of the device with handle on the bolt, andfastening latch omitted.

Fig. VIII is a front elevation of the handle appearing in Fig. VII.

Fig. IX is a detail of the handle as secured upon the bolt shown in Fig.VII.

Like characters refer to like parts in the "iews.

In Fig. I is shown a window frame 1, one

side of an upper sash 2 and lower sash 8 with the device installed ineach sash, and showing in dotted lines the recesses 4; to receive thebolt. Metal sleeves 5 may be driven into the recesses to protect theadjacent wood. A horizontal opening 6 is bored in the stile of eithersash. A transverse opening 7 is bored in the stile centered on theopening 6. Such an opening is seen in Fig. II. The fastener consists ofa bolt 8. It is slightly tapered on one end, which allows it to enterthe receiving recess without catching on adjacent parts. The handle slottherein. The handle 9 has the short slot 10. It has a transverse opening10* through the slotted parts, allowing the bolt8 to be driven throughit. In this case the bolt is corrugated at 11 and the slotted part ofthe handle is spread in order to cause it to grip the bolt rigidly, asshown in Fig. IX. The handle 12 has a long slot 13. This handle has atransverse o ening 14 and the bolt on which it is place has a centralgroove 15. A fastening latch 16 is inserte in the is made with a shorterlong longitudinal the opening 7 when the bolts and handle are i inplace. The escutcheon 18 has a horizontal slot 19 through which the bolthandles extend outwardly and sutliciently to permit them to be graspedto move the bolt. In the case of, the handle 12 the escutcheon 18has asmall slot 20 in the lower edgeof its horizontal s ot. fastening latch16 and hold the boltjthrough the handle from being moved in eitherdirection. 3 a

The operation of the bolts is clearly apparent from the illustrations.If desired, another latch slot may be made in the escut-cheon. The slotsshould of course be positioned according to the use of the fastener. Forinstance, on windows there would be one latch slot only to preventoperation of the bolt from the outside. On doors the latch slot might bepositioned for a hold open function. 'The construction of the escuteheon adapts it to serve also as a lift. The

handle tothe bolt allows use of a bolt of small diameter and this willreduce movement! friction to a minimum. The device may be installed insash or doors without removal of any part thereof or marring the finish.7 Only two bored holes are required for complete installation and thedevice may The escutcheohhas a recess 18.

This slot 20 is adapted to receive the be used on very narrow and thinstiles. The device is ornamental and when fastened is invisible from theexterior. Thisvbolt may be installed without exact alignment or positionof parts. That is to say, the bolt may be set at varying depths inthestile or it may be slightly above or below the center: of the escutcheonslot without impairing its operation. The device also tends to preventthe annoying rattle in. looselyfitted windows. No change in detail fromregular standards is required for its reception. An outstandingadvantage of the device is that ,windows may be fastened with the sashespartly open. The top sash may thus be down a few inches and the lowersash raised a few inches and the belts cannot then be tampered with fromthe outside, as they cannot then be reached and operated. It willfurther be observed that the fastener being installed in the lower partof the upper sash, that sash might be lowered with an. openin of onefoot at the top and the lower sash might be raised a few inches, and thelower sash would then cover the fasteners in the upper sash. In thisposition the upp fasteners would be inaccessible and the low fastenerscould not be reached through the loweropening and both operated at thesame time. The construction is so simple that my fastener can bemanufactured at a very low cost. Its cheapness and effective operationcharacterize its novelty and utility.

I claim:

1. In adeviee of the character described 7 the combination of; a bolthandle having a and the handle and latch being adapted to receivethrough their aligned openings a bolt and to oscillate thereon.

2. In a device of the character described the combination of; a boltslightly tapered at one end and having a circular groove in its centralportion, a handle having a longitudinal slot therein of convenientlength and a transverse opening near one end adapted to receive the bolttherein and to allow the handle to oscillate in the bolt groove whenpositioned therein, and a thin fastening latch having an opening throughone end, said latch being adapted to be inserted in the handle slot andto receive the bolt through its opening in alignment with the handleopening and to oscillate upon the bolt in its grooved portion.

3. In a device of the character described the combination of; a boltslightly tapered at one end and having a circular groove in its centralportion a handle having a longitudinal slot thcr of convenient lengthand a transverse opening near one end adapted to receive the bolttherein and to allow the handle to oscillate in the bolt groove whenpositioned therein, a thin fastening latch having an opening through oneend, said latch being adapted to be inserted in the handle slot and toreceive the bolt through its opening in alignment with the handleopening and to oscillate upon the bolt in its grooved portion, and anescutcheon. having a recess therein and a slot adapted to receive thehandle and fastening latch. through the same, said escutcheon alsohaving a small transverse slot in one edge of the slot first described,said small slot being adapted. to receive therein the fastening latch.
